Agreement and the objective test
Certainty- agreement must not be vague
Objectivity- law not concerned with parties inner intentions, but what parties said or did, and what led the other party (or reasonable person) to believe (RTS v Miller)
Implications of objective approach
-a person may be bound by a mistake in the offer (centrovincal Estates v Merchant Investors Assurance)
-a person may be bound by a mistake in the acceptance (smith v Hughes)
-mistaken offers, would the person have realised a error? (Hartog v Shields)
-if the Offeror induced the mistake, they may not be able to enforce the contract (Scriven v Hindley)
